Why do people care about ass so much

Doesn't matter if you are gay or straight or even a guy or a female, why is there such a fascination with buttocks?
My theory is that it's close to the genitals that why.

There's always a fascination with body parts that are almost always covered. Especially curvy body parts.

I don't give a shit about ass. I don't even notice them. Not even Nick Jonas' ass. All I see are faces. And then VPLs.

The ass is a beautiful thing

It's both the appearance and the musk, I think. The male asshole has a lot of androgenic hair (a beautiful secondary sexual characteristic), and lots of enticing pheromones as well.

I check the ass before I check the crotch. Not into big cocks but do love a nice ass.

An old friend of mine could go on for half an hour about the smell of his favorite tricks' and boyfriends' assholes.

For me, it's all about the cheeks. I don't like "hole" or smells at all.

It's primal. An ass tells you about a person's fitness, youth and sexual availability (tight clothes, etc.).
Cats smell each others stool and can determine age, sex, health and position in the hierarchy.
"The Missionary Position" is a relatively modern invention. Most mammals fuck doggy-style, so the ass has to turn you on.

I believe a plump male ass indicates fertility.

It's a thrusting issue. Men with strong asses are more effective at depositing their seed and ensuring it successfully mates with an egg.
Seriously. It's evolutionary biology.

Many reasons. First of all the ass is an erogenous zone. Caressing the cheeks, stimulating the nerve endings of the anus, and, for men, stimulation of the prostate can be extremely exciting. Then, there are the aesthetics. The ass, like the genitals is at the center of the body vertically and so it is a focal point. Its contours are a major feature of the body.
For these reasons, an appealing ass can be very exciting. How does this break down? Well, of course that depends on what one considers an appealing ass. As with all parts of the body, there is no universal consensus and the majority view, or what would appears to be such by popular conception, changes from place to place and era to era.

It's the perfect expression of the symmetry of the body.
As R11 said, literally a focal point. Notice how all lines lead to anus.

I have loved the male ass in all its variations since I was a young child. Given a choice of seeing a guys dick or his ass, I would opt for seeing the ass. All dicks are good. Each ass is it's own wonderland.

I love ass.

What r10 said. Dudes with more ass are better lays. The have more muscle power in that area.

I agree, skinny asses or thin lips spell doom in the bedroom

You have to have-a ass in moderation! You cannot have ass all the time!
